Work performed includes repairing 3,000 feet of track and 60,000 feet of cable inside the tube that carries G service between Brooklyn and Queens.

The repairs are part of NYCT's Fix & Fortify initiative to repair and strengthen portions of the system damaged as a result of Superstorm Sandy. MTA NYCT has had to close down that segment of subway to train traffic for an extended period for the work, which allows workers to tackle the damage left behind by last year's storm without interruption.

Nine of the subway system's 14 under river tubes saw some level of water during the storm with the Montague R and Greenpoint G Tubes hit the hardest. Though service was restored in the wake of the storm, the damage caused by the corrosive effects of the salt water required the removal and replacement of tracks, cables and other systems and equipment.

MTA NYCT has reached the point where 127 linear feet of bench wall has been completely demolished and replaced along with 970 linear feet of duct. While the tube work is ongoing, maintenance forces have also taken the opportunity to perform maintenance chores in nearby closed stations. The appearance of the 21 St. and Greenpoint Av. stations has been spruced up with the application of fresh paint on 95,000 square feet of ceiling and columns. Workers also took the opportunity to rehabilitate 27 stairways.

The next round of work is scheduled for the weekend of September 27-30. Rounding out the year, there will be three more weekend closures following.
